GENUS XIX. 
MARSHALLIA, Nutt. THE MARSHALLIA. 
Lin. Sijst. SYNGENESIA JEGNALIS. 
turbinate, hairy. Pappus consiatiug of five equal elliptic, acuminate, 
entire palea. 
Generic Chaiuctek. — Involucre generally in two series. Scales 
linear, lanceolate, equal. Receptacle convex, palea linear, acute. 
Corollas tubular, five-toothed, hairy on the outside, Achenium 
Description, &c. — Natives of North America, with entire, alternate leaves, and a head of flowers somewhat 
resembling that of clover. The genus, we are told, in the Botanical Magazine (Vol. 65) was " named in 1791, 
in compliment to Mr. H. Marshall, who wrote a history of the trees and shrubs of North America,'" to which 
country, and Mexico, the species are entirely confined. 
1.— MARSHALLIA CJISPITOSA, Nutt. THE TUFTED MARSHALLIA. 
Enor«ving8. — Bot. Mag. t. 3704 ; and oar fig. 4 in Plate 50. late, entire. Scales of the involucre oblong, linear, obtuse. Palea of 
Specific Characteh. — Smooth, tufted. Stem simple, without the receptacle linear, 
leaves, and with only one head of flowers. Leaves elongated, lanceo- 
Description, &c. — A singular- looking plant, wliich, when many heads are grown near together, has very 
much the appearance of Gigantic Thrift. It is a native of Texas, whence it was introduced in 1837. It is not 
quite hardy in British gardens, being killed by severe frosts ; and it is hardly worth the trouble of protecting. 
I have, however, mentioned it as a curious plant, and to give my readers an idea of what kind of plant it is, if 
they should see its name. Besides, it may please many persons, though it does not happen to take my fancy. 
It is propagated by seeds, and should be grown in light soil. 
M. LANCEOLATA, Deo. 
A native of Carolina, introduced in 1812. It has lilac flowers, which appear in August and September, 
about a month later than those of M. cwspitoia. 
M. LATIFOLIA, Deo. 
A native of Carolina, with lilac flowers and broad leaves. Introduced in 1806. It was on this species that 
the genus was founded. Micheaux had called it Persoonia, but another genus having been called Persoonia by 
Sir J. E. Smith, Persoon called it Trattinickia. This name having been also appropriated by Willdenow, it was 
lastly called Marshallia, a name which now seems to be generally adopted. 
M. ANGUSTIFOLIA, Deo. 
This species has never been introduced. It has narrow leaves, as the name imports. 
GENUS XX.

Lm.Syat. SYNGENESIA SUPERFLUA. 
Generic Character. — Florets of the ray ligulate, lanceolate, numerous. Calyx imbricate, subequal, hemispherical. Leaves tnuefa cot, 
flowers terminal. 
Description, &c. — The common Chamomile is only grown in gardens for medicinal purposes, but the Chinese 
Chamomile is so elegant a plant that it well deserves culture. The word Anthemis signifies covered with 
flowers.
